BACKGROUND: The ability to return to running and sports participation after lower extremity limb salvage has not been well documented previously. Although the ability to ambulate without pain or assistive devices is generally a criteria for a good limb salvage outcome, many patients at our institution have expressed a desire to return to a more athletic lifestyle to include running and sports participation. The purpose of this study was to investigate the types of athletic endeavors our high-energy lower extremity trauma patients were able to pursue after limb salvage...

AIM: The most strategic part of a triathlon is the cycle-run transition. However, all the studies about this situation have been carried out in laboratory conditions and there is a need to perform this kind of study during competition, when the triathletes are highly motivated and the effort is maximum.1 Therefore, the aims of the present study were: 1) to determine the effect of prior 40-km cycling on the 10-km running kinematics during a Triathlon World Cup competition, and 2) to examine the possible differences between males and females...

OBJECTIVE: To detail the progress of a novice triathlete with an unusual mechanism of a tibialis posterior strain who underwent successful conservative treatment and rehabilitation. Tibialis posterior tendon dysfunction will be discussed as it relates to the case. CLINICAL FEATURES: The clinical features of tibialis posterior dysfunction are swelling and edema posterior to the medial malleolus with pain and an inability to weight bear. This injury may occur in endurance athletes such as triathletes, most often occurring during running...

The aim of the study was to verify whether an overloaded training (OT) in triathlon deteriorates running kinematics (RK) and running economy (RE). Thirteen well-trained male long-distance triathletes (age: 28.1 +/- 4.3 yrs; V.O (2max): 65.0 +/- 3.1 ml O (2) . min (-1) . kg (-1)) were divided into two groups: completed an individualized OT program (OG; n = 7) or maintained a normal level of training (NT) (CG; n = 6) for a duration of 3 weeks. Every week, each triathlete completed a standardized questionnaire to quantify the influence of training loads on mood state...

The aim of this study was to determine the effect of prior cycling on EMG activity of selected lower leg muscles during running. Ten elite level triathletes underwent two testing sessions at race pace: a 40 km cycle followed by a 2 km run (CR) and a 10 km run followed by a 2 km run (RR). EMG data from selected lower limb muscles were collected at three sections of each run (0 km, 1 km and 2 km) for six strides using a portable data logger. Significant differences (p < 0.05) between condition were found for the level of activation (Lact) for biceps femoris (BF) during stance and vastus lateralis (VL) during flight and stance...

PURPOSE: The purposes of this study were first to compare the physiological responses during a triathlon where cycling was performed alternatively with another cyclist (alternate draft triathlon, ADT) or continuously behind him (continuous draft triathlon, CDT), and second to study the incidence of these two drafting modalities in cycling on the subsequent running performance done during a simulated triathlon. METHODS: Ten male triathletes of national level performed a sprint distance triathlon (0...

The aim of this study was to investigate the increase in energy cost of running occurring at the end of a triathlon and a marathon event and to link them to the metabolic and hormonal changes, as well as to variations in stride length. Seven subjects took part in 3 experimental situations: a 2 h 15 min triathlon (30 min swimming, 60 min cycling and 45 min running), a 2 h 15 min marathon (MR) were the last 45 min were run at the same speed as the triathlon run (TR), and a 45 min isolated run (IR) done at triathlon speed...

Seventy-one athletes with 74 stress injuries to the femur were studied using a case-controlled design. Forty-three were females (26.6 yrs) and 28 were males (31.2 yrs). Each patient had exercise-induced pain in the hip, groin or thigh and a Tec-99m-MDP bone scan showing focal uptake of radionuclide in the femur. Running was the most common activity at the time of injury (89.2%) followed by triathlon (4.6%) and aerobic dance (4.6%). Thirty per cent of the runners had increased their training duration immediately prior to their first symptom...
